ARPA-E Under Trump
Some of the work of the U.S. Department of Energy's advanced research wing fits fine with Trump's priorities, but analysts worry the next generation of solar tech could suffer
Can Synthetic Inertia from Wind Power Stabilize Grids?
Wind farms can emulate the rotational inertia that conventional power plants provide to stabilize power grids. Next-generation technology will do it even better
Arpa-E's $85 Million Plan to Build a Battery the Size of the Grid
Or something like that
Wind Battles Coal for Access to China’s Grid
Coal interests oppose technologies and rules that would prevent the waste of pollution-free power
Wind Could Provide 26% of China's Electricity by 2030
Despite increasingly severe curtailment of Chinese wind farms in favor of coal-fired generation, a first-of-a-kind energy dispatch model finds that the country can accommodate a lot of additional wind power
Solar and Wind Energy From the Same Device
Candy-bar-sized device could produce solar and wind power from city rooftops
Why China's Wind Energy Underperforms
In 2012, low quality turbines and delayed grid connections wasted as much of China’s wind power potential as forced outages. But today’s picture could be quite different
Renewables Grew to 15.5% of US Electricity Capacity in 2014
A report published by NREL found that more than half of energy capacity added in the US in 2014 was renewable
An All Wind, Water, and Solar Grid Will Be Stable Without Batteries
Energy could be stored as heat, hydrogen
Putting California Wind Power Out to Sea
Proposals for floating wind farms such as Trident Winds' California project no longer sound like science fiction
Taming Wind Power With Better Forecasts
Sophisticated weather simulations are making wind power more grid friendly
Hawaii Votes to Go 100% Renewable
Hawaii’s legislature has voted to set the first 100-percent renewable power goal for a U.S. state, but it’s got growing global company
U.S. Hydropower Fleet has Upside Power and Storage Potential
The Energy Department's first comprehensive hydropower assessment shows steady growth and plenty of headroom, especially for pumped hydro energy storage
Jeremy Rifkin on the Internet of Things and the Next Industrial Revolution
Will the Internet of Things be a technological and economic panacea?
Costa Rica Runs on Renewables For 75 Days
Heavy rainfall boosts clean energy and lowers power prices
EPA Coal Cuts Light Up Washington
At FERC’s technical meeting on EPA’s plan to stub coal power’s carbon footprint, sparks fly over the yawning divide between anxious coal-dependent states and believers in clean energy
Will Shuttering Coal Plants Really Threaten the Grid?
Grid studies claiming EPA's coal power rule could destabilize transmission systems amount to "garbage" science, according to renewable energy advocates
Does Hawaii Need a Unified Grid?
NextEra Energy proposed a merchant Maui-Oahu power link to expand use of renewable energy. Now it wants to buy Hawaii's grid
Nanoballs Inflate Voltage Capacity of Power Cables, Save Energy
A small amount of carbon nanoballs added to plastic insulation means a big boost in voltage
China Dominates the World of Wind, but the U.S. Wind Energy Market Rebounds
Nearly half of all wind power installations in 2014 occurred in China. Offshore projects could drive future growth
